When Pee-wee suggests they 'play library', everyone is seen reading a book: the Flowers have "Splendor in the Grass". Chairry reads "Pygmalion". For Globey, it's "Around the World in Eighty Days" (of course). The Fish read "Moby Dick", and Miss Yvonne peruses "Part Time Dog, Part Two". Pterry looks at "My First Reader", while Miss Yvonne is now giggling as she listens to headphones, while holding an album cover for "Kitty Rallens 'My Coloring Book' - And Her Other Great Hits". Librarian Pee-wee asks Miss Yvonne to "please keep your laughter to yourself - some of us are trying to concentrate!".
The secret word in this episode is "end", which was said and screamed at 12 times.
